Kazuma Narusawa
Kazuma is a rich, well known computer games programmer. He often helps to find information on his laptop computer, which he carries around with him all the time. At first after learning that he was a member of Class Q (which at the time was believed to be the lowest) he tried to get transferred in Class A. However, when his classmates came to his aid when he was in trouble he changed his mind, preferring to stay with his friends. Kazuma has a friendly rivalry with Kinta due to their different approaches to detective work. Kazuma and Kinta are often the butt of each others jokes. He is a very smart prodigy, but he can't get right answers without his "lucky" hat as implied in episode 2; he seems to get over this flaw by the end of the TV series. (Source: Wikipedia)
